Started off down a rabbit hole about roofing membranes.
The ever relisble Internet aided by AI suggested that the service life for tar paper was about 15 years. and a modern roofing membrane was 20-25 years.
This seems unreasonable to me.
Strip off the roof tiles and replace the membrane every 20-25 years?
I don't know anywhere that does this.
I do wonder if AI is mixing up the durability of a felt flat roof with a pitched roof with tiles.
Has anyone had to refurbish a pitched roof in this manner?
As an indication, I think out 1930s semi is still on the original tar paper (or whatever).
